Particle Size Analyzer Analysette 22 NanoTec

The Laser Particle Sizer Analysette 22 NanoTec extends the measuring range of usual instruments down to nanometer range.

With a measuring range of 0.01 – 2100 µm in a single instrument, the Analysette 22 NanoTec is the ideal, universally applicable, Laser Particle Sizer for the effective and reliable determination of particle size distributions.

The NanoTec has a modular concept: a common central measuring unit and 4 different dispersing units.

Switching from one dispersing module to another is quick and simple and does not require any tools:

  • Wet dispersion unit, with adjustable suspension volume, pump speed and ultrasonic power
  • Dry dispersion unit, with high-frequency feeder
  • Falling chute, for the measurement of powders in their original state
  • Small volume wet dispersing unit, for use of organic solvents

An auto sampler, capacity 26 samples, can be used in combination with the standard liquid dispersing unit.

Measuring range 0.01µm (10 nanometers) to 2100µm

The patented Inverse Fourier design with movable measuring cell used by FRITSCH, offers a unique high resolution of up to 110 Particle Size Classes.

Two lasers technology with automatic alignment and user-friendly software.

Applications:the NanoTec is perfectly suitable for the use in quality control and process control, as well as research and development.

In order to reliably capture the nanometre range, a laser is used for the measurement of the backward scattered light. This laser beam illuminates the sample directly positioned in front of the detector from the back, through a micro-hole in the centre of the detector. The small distance between the measuring cell and the detector creates an unbeatable favourable geometry for the exact measurement of the light signals.

Due to the combination of the 2 lasers with two different measuring cell positions and without any alterations, the measuring ranges can be simply selected via the software.

For the proof of the backward scattered light, the same detector is always used for all measuring area. Due to the combination of 2 positions, high resolution measurements of up to 110 effective channels are possible.

  • Dual-laser technology for forward and backward scattering
  • Open configuration of the measuring processes
  • High resolution through the analysis of 110 size classes
